A powerful satellite is on its way to join Inmarsat’s Global Xpress fleet to deliver seamless global Internet and data connectivity to airline passengers, maritime crew and government users after successfully launching atop a SpaceX Falcon 9 rocket on Monday.

Sustaining a rapid turnaround pace at the company’s Kennedy Space Center Launch Pad, a SpaceX Falcon 9 rocket lit up its engines on Thursday in a final end-to-end test ahead of liftoff as early as Monday night with a high-power communications satellite for London-based operator Inmarsat.

The Inmarsat 5-F4 satellite arrives at SpaceX’s processing facility in Florida after a cross-country trip from Boeing’s El Segundo, California manufacturing base to enter final preparations for a May 2017 liftoff atop an expendable Falcon 9 rocket.
